MySQL备份之Xtrabackup 2.1.7 源码安装
转载请注明出处：http://blog.csdn.net/guoyjoe/article/details/51785118
Xtrabackup主要包含两个工具
xtrabackup：是用于热备份innodb, xtradb表中数据的工具，不能备份其他类型的表，也不能备份数据表结构；
innobackupex：是将xtrabackup进行封装的perl脚本，可以备份和恢复MyISAM表以及数据表结构。
1.下载Xtrabackup备份工具，选source code安装包
https://www.percona.com/downloads/XtraBackup/LATEST/
2.在线安装文档
https://www.percona.com/doc/percona-xtrabackup/2.2/index.html
3.解压
tar -xzvf percona-xtrabackup-2.1.7.tar.gz
4.安装perl环境(DBI/DBD)
yum install perl-DBIx-Simple.noarch
yum install perl-DBD-MySQL.x86_64
yum install perl*
5.Prerequisites
$ yum install cmake gcc gcc-c++ libaio libaio-devel automake autoconf \
bison libtool ncurses-devel libgcrypt-devel libev-devel
6.在源码目录确认mysql-5.6.15.tar.gz包（xtrbackup2.1的版本自带有，这步不用操作）
一是通过执行命令 AUTO_DOWNLOAD="yes" ./utils/build.sh xtradb ,允许build.sh自行下载
二是通过手动拷贝 mysql-5.6.15.tar.gz和libtar-1.2.11.tar.gz两个文件
AUTO_DOWNLOAD="yes" ./utils/build.sh xtradb
7.开始编译
$ ./utils/build.sh #根据版本确认build.sh的参数
$ ./utils/build.sh innodb56 #开始编译
8.把xtrabackup_56复制到/usr/bin下
cp /u01/percona-xtrabackup-2.1.7/src/xtrabackup_56 /usr/bin/
9.利用Innobackupex备份
./innobackupex --socket=/u01/my3306/run/mysql.sock --defaults-file=/u01/my3306/my.cnf /backup/mysql/3306 > /tmp/2.log
[mysql@xiangxingedu percona-xtrabackup-2.1.7]$ ./innobackupex --socket=/u01/my3306/run/mysql.sock --defaults-file=/u01/my3306/my.cnf /backup/mysql/3306 > /tmp/2.log
